HP for me too! After selling a few CD's back to the CD store and drinking only 5 nights a week, I was able to afford the super duper HP48S from the college book store.
To this day, 10+ years later, I'm still using it for engineering work. It helped that I collected a bunch of programs and created a bunch of programs while I was in school. They are useful...well, the ones I remember how to use
I've dropped it several times and had to recover the memory once (phew!), and it's still rocking on! I swear that thing is built for military abuse
But yes, Tony is right, a laptop with Matlab would work better
I love my HP.
OH CRAP! I'm a NERD!
